Joe,
That antenna has a 200 ohm feedpoint .... 4:1 balun required .... you will
never blow the 1/2 wave coax balun.

Subject: [Towertalk] telrex 20m646 feedpoint impeadance
I am getting ready to put up a telrex 20m646 (20 meters, 6 elements, 46'
boom) that I have cleaned up, however I am wanting to put a commercially
made balun on the beam instead of the 1/2 wave piece of coax used for a
balun from the factory. Does anyone know the feedpoint impeadance of this
antenna? I am trying to determine what type of balun I need ( 1:1, 4:1 etc.)
.
Thank you for all input.
